Phenol is an acid but does not react with sodium bicarbonate solution. Why?

Hello Student
Phenol is acidic in nature but not that much acidic to react with NaHCO3. Phenols are weakly acidic in nature. They turn blue litmus red and react with alkali metals and alkalies to form their salts. Phenol is a weaker acid than carboxylic acid, hence does not react with sodium carbonate and sodium bicarbonate.The acidic character of phenol is due to the presence of polar O-H group. Because of larger electro negativity of oxygen atom, the electron pair of O-H bond is withdrawn more towards O and H+ ion can be easily released in aqueous solution

Phenol is weaker acid then carboxylic acid because phenol does not react with sodium carbonate but sodium bicarbonate,wher w as carboxylic acid react with both sodium carbonate and sodium bicarbonate
